Vulnerabilities are known advisories that Grype matches against the dependencies declared in each project's release source (manifests and lockfiles, including development and build dependencies). A match does not mean the tool is exploitable: the vulnerable code may be unused, test-only, or not shipped in the released binary. KEV: listed in the CISA Known Exploited Vulnerabilities catalog. EPSS: FIRST's estimated probability of exploitation in the next 30 days. Both describe the vulnerability in general, not its exploitability through this tool; a match in a workflow file refers to a GitHub Action, not to shipped code. Released binary is only analyzed for Go tools with a Linux release binary; other tools show not analyzed.
